On the startup screen (where id & password are entered)there is a huge button that says register expansion. This takes you to a subscription page with a large button "registration key" towards the bottom. The line above the "key" button mentions collectors edition, jboots, monkeys, and adding expansions. I'm not sure if the "key" button is for a specific product (such as the collectors edition) or for all expansions. Anyway, clicking on the "registration key" button leads to the "key consumption" 20-digit account key boxes. Entering in the account key inside the DoF box causes the boxes to clear. Seems rather straightforward but non-functional. Rather frustrating. I don't know how to proceed. I guess I'll just buy EoF bundle and try at a later time to register the expansions.
